- remove unused String "finalTitle" in NotificationMgr (accidentally
included in one of the Moto changes)

- tweak bottom margin of one CallCard text field to avoid cutting off
descenders

- remove the unused PhoneUtils getCompactName() methods

- remove unused CallCard showCall* methods

- remove useless CallCard reset() method

- When the radio technology changes, have PhoneApp call a new InCallScreen
method that unregisters then re-registers for phone state events.
(Even though we don't have any devices yet that can switch on the fly
between GSM and CDMA, the code still ought to do this.)
